Common reasons why the variable frequency air compressor cannot start normally;
first, if the contactor is not closed, it is mainly the electrical cause of the air compressor
(1) First check whether the power supply of the air compressor is connected correctly, whether the power switch is closed, whether the power fuse is blown, and whether the power supply voltage reaches more than 90% of the rated voltage.
(2) Check whether the components of the air compressor power supply pressure relay are damaged and whether the given value of the pressure relay is appropriate.
(3) Check whether the working medium in the temperature sensor of the air compressor thermostat leaks, whether the parts of the controller are damaged, and whether the temperature indication position is adjusted correctly.
2., if the contactor has been closed and the inverter air compressor cannot be started, it is likely that the motor fails or the air compressor has a mechanical failure;
(1) Check whether the phase sequence of the motor wiring is correct, and use a multimeter to test whether the motor winding is short-circuited or open.
(2) Check whether the running parts of the air compressor are stuck on the shaft due to insufficient lubrication or too small clearance. If there is a phenomenon of holding the shaft or sticking the cylinder, the impurities in the lubricating oil should be removed, the new lubricating oil should be replaced, and the oil path should be smooth.
For the question of "which is better to buy oil-free or oil-free air compressor", the answer depends on your specific needs and use environment. The following is a brief comparison of oil-free and oil-free air compressors, as well as water-lubricated oil-free air compressors for Shanghai Granklin Group.
The air pressure of the air compressor is not a fixed value, but is determined according to the type, specification, use and user needs of the air compressor. The following are some common air compressor factory air pressure range and related information: 1. air compressor factory air
Oil-free air compressor does not need to add oil in the working process. This is because the oil-free air compressor adopts a special lubrication method, usually using water or other oil-free lubricants instead of oil, so as to ensure that there is no contact with oil during the compression process, and the discharge compression is guaranteed from the source
Screw air compressors are generally not recommended for frequent start-up. Frequent start-up may cause additional burden and wear on the electrical system, motor and mechanical parts of the air compressor, shortening its service life. In addition, the current impact at startup may also stabilize the grid.
The scientific calculation of plant gas consumption is the core link to optimize the compressed air system and reduce operating costs, which needs to be systematically evaluated in combination with actual production scenarios and equipment characteristics. The specific calculation can follow the following steps: 1. basic gas consumption accounting 1.
The relationship between the pressure generated by the air compressor and the distance is a complex physical phenomenon, involving the combined effect of multiple factors. The following is a detailed description of this relationship: When the air compressor is working, it generates pressure by compressing gas. The magnitude of this pressure is not only
The difference between oil-free screw and micro-oil screw air compressor is mainly reflected in the following aspects: Working principle and structure: Oil-free screw air compressor does not contact oil at all during compression. There is no direct contact between its rotors, there is a certain gap, and dependent
The air filter (air filter) replacement cycle of an air compressor depends on a number of factors, including the environment in which the air compressor is used, air quality, running time, and the quality of the filter. Generally speaking, the replacement cycle of air filter is recommended to be every 2000 to 4000 hours or according
Air compressor fault prevention strategy and implementation guide As the core power equipment of industrial production, the stable operation of air compressor is directly related to the production efficiency and operating cost of enterprises. Failure prevention needs to start with full lifecycle management of equipment and build a system that covers daily dimensions.
Compressed air standards for the mineral water industry mainly relate to the purity, water content and possible microbial contamination of compressed air. The following is a detailed summary of these standards: 1. purity standards Compressed air should be oil-free to ensure that there is no oil in the air flow.
